図4や特許文献1に示された従来のオイルシールによる回転軸部分の気密性保持については、特にパン生地材料の粉粒子がオイルシールのリップと回転軸との隙間に入り込み、グリス(潤滑剤)と混ざり合って擦れ合い、黒くなったグリスが染み出て食材に混入する。オイルシールの材質やグリスは食品衛生法に適合したものを使用しているが、食材に混入することは見た目にも好ましいことではない。   Regarding the airtightness maintenance of the rotating shaft portion by the conventional oil seal shown in FIG. 4 and Patent Document 1, in particular, the powder particles of the bread dough material enter the gap between the lip of the oil seal and the rotating shaft, and grease (lubricant) The grease becomes dark and oozes out and mixes with the ingredients. The material and grease used for the oil seal conform to the Food Sanitation Law, but it is not preferable to mix it with food.

しかも、食材が軸受け部分に入り込みオイルシールや回転軸を摩耗させ、その結果機密性が悪くなり、水等の液体食材が軸受け部分を通って容器外に漏出していた。そしてグリスが染み出るような不具合が発生した際の修理の時には、軸継ぎ手部を回転軸から外して行うことになるが、オイルシールがすり減っており、また回転軸や軸受けメタルもその隙間に入り込んだ粉粒子によって摩耗しているので、結局のところ回転軸などを取り付けた状態で軸受けケースを丸ごと交換せねばならず、コストがかかり又家庭用撹拌装置でありながら家庭ではその交換や修理ができなかった。   Moreover, the food material enters the bearing portion and wears the oil seal and the rotating shaft. As a result, the confidentiality deteriorates, and liquid food material such as water leaks out of the container through the bearing portion. When repairing a problem that causes grease to leak out, the shaft joint is removed from the rotating shaft, but the oil seal is worn out, and the rotating shaft and bearing metal also enter the gap. Since it is worn by dust particles, the entire bearing case must be replaced with a rotating shaft attached, which is costly and can be replaced and repaired at home even though it is a household stirring device. There wasn't.

また、特許文献2では食材がオイルシールと回転軸との間に入り込まないように強制的にエアーを送るようにしており、家庭用としてはコスト面や構造面で適しているとは言えない。   Moreover, in patent document 2, it is trying to send air compulsorily so that a foodstuff may not enter between an oil seal and a rotating shaft, and it cannot be said that it is suitable in terms of cost and structure for home use.

本発明は、以上のような問題点を解消し、一般家庭でも簡単に点検修理ができるように工夫した食材撹拌装置を提供するものである。   The present invention provides a food stirrer that solves the above problems and is devised so that it can be easily inspected and repaired even in a general household.

本発明の食材撹拌装置は、食材を入れる容器と、該容器外底面に取り付けた軸受けケースと、該軸受けケースの軸受け部を貫通して容器の内外に突出する回転軸と、該回転軸の容器内の上部に着脱自在に装着する撹拌羽根と、回転軸の容器外の下部に取り付け、駆動モータ側の駆動伝達部と着脱自在に係合してモータの回転力を前記撹拌羽根に伝達する軸継ぎ手部と、を備え、撹拌羽根を回転させて容器内の食材を撹拌するようにした家庭用食材撹拌装置において、
記軸受け部に自己潤滑性樹脂製の軸受け筒体を取り付け、該軸受け筒体内に前記回転軸を回転自在に貫通し、回転軸にはその周方向にフランジを設け、該フランジと軸受け筒体上端面との間に位置する回転軸に、摺動ワッシャーとクッションリング体とを該摺動ワッシャーが軸受け筒体の上端面に接するように重ねた状態で装着したことを特徴とする家庭用食材撹拌装置。
The food stirring device of the present invention includes a container for containing food, a bearing case attached to the outer bottom surface of the container, a rotating shaft that penetrates the bearing portion of the bearing case and protrudes into and out of the container, and a container of the rotating shaft An agitation blade that is detachably attached to the upper part of the inside, and a shaft that is attached to the lower part of the rotating shaft outside the container and that removably engages with a drive transmission part on the drive motor side to transmit the rotational force of the motor to the agitation blade. In a household food stirrer provided with a joint portion and rotating the stirring blade to stir the food in the container,
A bearing cylinder made of a self-lubricating resin is attached to the bearing, and the rotation shaft is rotatably passed through the bearing cylinder. A flange is provided in the circumferential direction of the rotation shaft, and the flange and the bearing cylinder A household food agitation characterized by mounting a sliding washer and a cushion ring body on a rotating shaft located between the end face and the sliding washer so that the sliding washer is in contact with the upper end face of the bearing tube. apparatus.

本発明の家庭用食材撹拌装置は、オイルシールや潤滑用グリスを使用していないので、食材の撹拌中に食材が回転軸周りの隙間に入り込むことがなくなり、また仮に入り込んだとしてもグリスを使用していないので、グリスが黒くなって食材中にしみこむことも全くなくなり、衛生的に撹拌作業ができる。   Since the household food stirring device of the present invention does not use an oil seal or lubricating grease, the food does not enter the gap around the rotating shaft during the stirring of the food, and even if it temporarily enters, the grease is used. Since the grease does not become black and does not penetrate into the food, it can be stirred hygienically.

又オイルシールがないので、食材が隙間に入ってオイルシールや回転軸を摩耗させることもないので、長年の使用でも回転軸部分のシール性の劣化は少ない。又回転軸部分の分解組立もオイルシールがないので、簡単におこなうことが可能である。   In addition, since there is no oil seal, food does not enter the gap and wear the oil seal or the rotating shaft, so that the deterioration of the sealing performance of the rotating shaft portion is small even after many years of use. Also, the rotary shaft part can be easily disassembled and assembled because there is no oil seal.

さらに本発明は、回転軸にフランジを設け、そしてフランジと軸受け筒体上端面との間に位置する部分に、摺動ワッシャーとクッションリング体とを該摺動ワッシャーが軸受け筒体の上端面に接するように重ねた状態で装着したので、クッションリング体の弾力を介して回転軸のフランジによって摺動ワッシャが下方(軸受け筒体上端面方向)に常時押圧されることになるので、食材が入り込みやすい箇所である軸受け筒体上端面と摺動ワッシャとの間が緊密状態に保たれ、容器内の水や食材がその隙間から外部に漏出することがなくなる。   Further, according to the present invention, a flange is provided on the rotating shaft, and a sliding washer and a cushion ring body are provided on a portion positioned between the flange and the upper end surface of the bearing cylinder. Since they are mounted in contact with each other, the sliding washer is always pressed downward (in the direction of the upper end surface of the bearing cylinder) by the flange of the rotating shaft through the elasticity of the cushion ring body, so that food enters. The upper end surface of the bearing cylinder and the sliding washer that are easy to maintain are kept in a tight state, so that water and food in the container do not leak outside through the gap.

本発明を、図1〜図3に基づいて説明する。図1はすでに説明したので、主として図2と図3を用いて説明する。なお図1で説明した構成要素と実質上同一のものには同一符号を付して説明する。   The present invention will be described with reference to FIGS. Since FIG. 1 has already been described, the description will be made mainly with reference to FIGS. Note that components that are substantially the same as the components described in FIG.

軸受けケース13はアルミダイキャストで縦断面逆U字状に構成され、その上面が容器2の外底面にネジ20により固定される。軸受けケース13の軸受け部13aは容器2の底面に設けた開口から容器内に突入され、その上端面を容器2の内底面と面位置にするか或いは少許上方に位置させる。軸受け部13aには縦方向に貫通孔が開けられ、この貫通孔にテフロン等のプラスチックからなる自己潤滑性を有する軸受け筒体21を圧入して取り付けてある。   The bearing case 13 is made of aluminum die cast and has an inverted U-shaped longitudinal section, and the upper surface thereof is fixed to the outer bottom surface of the container 2 with screws 20. The bearing portion 13 a of the bearing case 13 is inserted into the container through an opening provided on the bottom surface of the container 2, and the upper end surface of the bearing case 13 a is positioned on the surface of the inner bottom surface of the container 2 or slightly above. A through hole is formed in the bearing portion 13a in the vertical direction, and a self-lubricating bearing cylinder 21 made of plastic such as Teflon is press-fitted into the through hole.

軸受け筒体21の上端部には外方に伸びる環状の耳片21aが形成され、後述する摺動ワッシャ22との接触面積を大きくしてある。また、この環状の耳片21aの上面と軸受け部13aの上面とは略面一状態に構成してある。   An annular ear piece 21a extending outward is formed at the upper end of the bearing cylinder 21, and the contact area with a sliding washer 22 described later is increased. The upper surface of the annular ear piece 21a and the upper surface of the bearing portion 13a are substantially flush with each other.

回転軸5は、上部に撹拌羽根6を着脱自在に装着し、且つ撹拌羽根の回り止めを施した装着部5aと、その下部の周方向にフランジ5bを一体的に設けてある。また回転軸5の下端部には軸継ぎ手部4bにモールドされている雌ねじ24と螺合する雄ねじ5cが形成されている。   The rotating shaft 5 is integrally provided with a mounting portion 5a on which an agitating blade 6 is detachably mounted on an upper portion and a rotation stop of the agitating blade is provided, and a flange 5b in the circumferential direction of the lower portion. A male screw 5c is formed at the lower end of the rotary shaft 5 to be screwed with a female screw 24 molded on the shaft joint portion 4b.

回転軸5は軸受け筒体21内に容器内方向から挿入して回転自在に構成する。
そして、フランジ5bと軸受け筒体21の上端面21aとの間に位置する前記回転軸5に、摺動ワッシャー22とクッションリング体23とを該摺動ワッシャー22が軸受け筒体21の上端面21aに接するように重ねた状態で装着する。
The rotating shaft 5 is configured to be rotatable by being inserted into the bearing tube 21 from the inside of the container.
Then, the sliding washer 22 and the cushion ring body 23 are placed on the rotary shaft 5 positioned between the flange 5 b and the upper end surface 21 a of the bearing cylinder 21. The sliding washer 22 is connected to the upper end surface 21 a of the bearing cylinder 21. Wear in a stacked state so that it touches.

摺動ワッシャー22は厚み略0,3〜1mmのテフロン(デュポン社の登録商標)等の滑りやすい樹脂から構成されており摺動性が優れている。また、クッションリング体23は、摺動ワッシャー22の厚みよりも厚く(略2〜8mm)して、シリコンゴム等から構成してクッション性を持たせている。軸継ぎ手部4bは、硬質樹脂製からなり、その雌ねじ24を回転軸5の雄ねじ5cにワッシャ25を介して螺合して取り付ける。   The sliding washer 22 is made of a slippery resin such as Teflon (registered trademark of DuPont) having a thickness of about 0 to 3 to 1 mm and has excellent sliding properties. The cushion ring body 23 is made thicker than the sliding washer 22 (approximately 2 to 8 mm) and is made of silicon rubber or the like to provide cushioning properties. The shaft joint portion 4b is made of hard resin, and the female screw 24 is screwed onto the male screw 5c of the rotating shaft 5 via a washer 25.

以上により、回転軸5はそのフランジ5bと軸継ぎ手部4bとで軸受け筒体21を挟持する格好となり、そしてクッションリング体23の弾力が常に軸受け筒体21の上端面21a方向に摺動ワッシャ22を介して押圧することになり、それ故フランジ5bとクッションリング体23の隙間、クッションリング23と摺動ワッシャ22の隙間、摺動ワッシャ22と軸受け筒体21の上端面21aの隙間のすべて、すなわち食材が容器2外に漏出する回転軸5回りのすべての箇所が気密に保持されるのである。   As described above, the rotary shaft 5 is shaped so as to sandwich the bearing cylinder 21 between the flange 5b and the shaft joint portion 4b, and the elastic force of the cushion ring body 23 is always in the direction of the upper end surface 21a of the bearing cylinder 21 and the sliding washer 22 Therefore, the clearance between the flange 5b and the cushion ring body 23, the clearance between the cushion ring 23 and the sliding washer 22, the clearance between the sliding washer 22 and the upper end surface 21a of the bearing cylinder 21, That is, all the places around the rotating shaft 5 where the food material leaks out of the container 2 are kept airtight.

そして、摺動ワッシャ22などを交換する場合は、軸継ぎ手部4bを回転軸5から取り外せば、回転軸は簡単に軸受け筒体21から取りはずしができ、摺動ワッシャ等の交換が簡単にできる。   When exchanging the sliding washer 22 and the like, if the shaft joint portion 4b is removed from the rotating shaft 5, the rotating shaft can be easily detached from the bearing cylinder 21, and the sliding washer and the like can be easily replaced.

しかも、食材がそれぞれの隙間に入り込んでいないので、軸受け筒体21や回転軸5の摩耗が従来のオイルシールに比べ少ないので、従来のように軸受けケース13全体を交換する頻度がかなり少なくなる等の効果がある。   In addition, since the food does not enter the gaps, the wear of the bearing cylinder 21 and the rotary shaft 5 is less than that of the conventional oil seal, so that the frequency of replacing the entire bearing case 13 as in the past is considerably reduced. There is an effect.

上記実施形態は、本発明の一例に過ぎず、本発明の趣旨の範囲で適宜変形や修正を加えても、特許請求の範囲に包含されることは明らかである。   The above embodiment is merely an example of the present invention, and it will be apparent that the present invention is encompassed by the appended claims even if appropriate modifications and corrections are made within the scope of the present invention.
